rThis"invention"relates to aV device for distributing tobacco mass, particularly for1v portioning or tobacco mass in the manufacture of! cigar l bunches` or other tobacco product's It' is" anobjectof the' inventiontomake improved'provisions for removal ofitobaccomass of a" uniform a-ndseparable conditionMfrom-a stora'gere'servoir' to be furtherv handled,v forinstance' in the-manufacture 'of cigar llers.-

Another" object of the'inventionis to provide meansv forcontinu'ously presenting the tobacco niass in' a: storage reservoir' in aloose; uniform andireadily separable conditiontoa gripper, so as' to"ensure-that said gripper will :fetch required portions of the tobacco mass without unduly compressing said mass in-thereservoir.

Witiitheseand' other objectsin view, the invention comprises the combination and'arrangementt of elements-Hereinafter fully described and setfortlrin the claims appended hereto.

Figi 2 isan elevational view, partly in'seotion, takienon'the line II-1I*`in-Fig. 1', and

yFigs. 3 and'v lL are viewscorresponding with Figs; 1l and 2 respectively of'j another embodiment.

In'the embodimentaceording to Figs; 1' and12', thespacefor' the tobaccois laterallyl limited by two discs4 2L which-are each-attached to-a hori# zorltal, rotatably journalled shaft'l I. Eachfof the discs 2 has a cylindrical flange It;V andy the 35 ilangesk I6 are separated from' eachv other.' by a spaceY SLv At ther outer'lside of the discsv 2' are immovabldppright side Walls 25;.in7 which the shafts I are' journalled. The' discs- 2: are each imparted a step-'wise-'rot'ary movement byaidrivingirnech'an'ism. This` driving mechanism has a continuously rotating; driving shaft T to which is attached a' canidisc 8f, which actuates the one arm ofa bell'orank lever' 9Iwhich'is influenced by a spring 9m; whereas rat its'- other' armV ispivotally connected one end'ofl a rod lil. The other end of the rod iispivot'ally connectedto an arm I'I, turnable about th'eshaitv lf. The-arm I'I` carries a pavvlE IZiwhich is actuated by a spring |211 and meshesl with a ratchet wheelY I3 attached tothe shaft' Il .ety the reciprocating movement of the arm ii together withIt-hepawl I'2 the Wheelf I3 aswellasthe'shaft I1' and the discs 2 aremoved st'e-plwisein the directionof thea'rrow P.y Duriiigthe'retractive movement of the lever II with ,55 the pawl I rt'he ratchet! Wheel` I3 andthe parts rigidly connected to it are retained by the pawl IB which is actuated by a spring iSd. The anges IB have grooves 2l which are parallellto the axis of rotation of the discs 2 carrying the ilanges I6-, in which grooves rod shaped impellers 26- are' reciproc'ally. movable. For their movement, the parts 26 are provided with pins' 28 whichv project into groovesv 29, which are arrange'dincylindrical flanges 35 of the immovable walls 25 andthe bottom 3i! of the housing which is attached to the frame 2! At the rotation of the discs 2 together with vthe flanges I6 the impellers 26 are moved in the circumferential direction and, in turn, impel the lower layers of the tobacco mass, until said layers havelbeenfmoved* so far upwardsthat they fall dewnandfare thereby mixedwith the other parts ofthe tobacco mass; In thelower part of the container the-fimpellers Zpenetrate verydeeply intothetobacco inassso that the mass 1- is very effectively moved'iupwards and turned over.

Because-oi the laterally curved shape ofthe peripheralgrooves 291as shown in Fig. 2, the impellersi 26 are' atk their upward movement displaced longitudinally outwardly, so that the ends l jeoting from' theframe 2l. A short arm 43 is securedv to the arm Glland carries a rotatable toothedsegment 44 to which is secured the'left hand leg of the gripper I5. The toothed'segment 441 meshes with another toothed segment lwhichis rotatably mounted on the pin=39and securedtoanarm 45 which is pivoted to another arm 3111; The arm 31 is also pivoted to one arm 4'Iof azdouble lever which is pivoted on the shaft andthe'other arm lofwhich is pivoted to a linkrod 49; The rod tlSYis also pivoted to a lever lwhichvcarries al roller I which under the influence of a spring 52rides on a cam 53 secured to the shaft-1. The operation of the gripper I5 is'not obstructed by the impellers 25 as the impellers in the space 3 are moved out of the sphere ofI the gripper l5` andthe arm lli. After leaving the vsphere ofKA the gripper the impellers 25 at their downward movement are again moved inwardly and introduced into the tobacco mass.

The embodiment illustrated in Figs. 3 and 4 differs from the one now described only with regard to the construction of the impellers and the parts serving for their movement. Otherwise, they operate fundamentally in the same manner. In this second embodiment, the impellers 26a are directed inwardly and attached toflexible arms 3|, or they constitute a bent part of said arms. Ring sector shaped guide plates 33 serve to control movements of the impellers and are attached to the inner edges of the flanges 35 of the housing. When the impellers 26a at their upward movement engage the front edge 32 of the plates 33 they are, on account of the oblique direction of the latter against the resistance of the flexible arm 3l, forced aside outwardly until they reach the position shown at the top of Fig. 4. Then, in their outer position, they slide further on the inner surface of the plates 32 until they reach the rear edge 34 of the same. After passing the edge 34 the impellers 26a again yield inwardly into the position shown at the bottom of Fig. 4.
